Definition from IAI: An IfcCrewResource represents a type
of resource used in construction processes, i.e. construction crew resource. A
construction crew resource typically includes labor resource, equipment
resource, material resource, subcontractor resource, as well as other crew
resources. Construction crew resources are partially or wholly consumed, or
occupied in a construction process (i.e. IfcTask). Since
IfcCrewResource represents the resource types, individual persons are
not required to be identified and linked to the crew resource, while they can
be associated if needed.

Use Definition
The IfcCrewResource is enabled to contain other crew resource
types (i.e. crew resource type nesting) through its relationship to
IfcRelCrewContainsResources. The WHERE constraints of the entity define the
mechanism of how this nesting can be achieved. Also note that in practice, when
defining a crew resource type, a set of process types that the crew type is
suitable for, are also identified. However, this is not handled in the current
version of the IFC Model as process types are not identified.
